In high speed web perfecting rotary presses where quick drying inks andweb heating and cooling units are employed, it is very desirable thatthe several units be so located with respect to each other as to producethe best results while occupying a minimum amount of space.

The object of my invention is to so locate the printing and combinedheating and cooling units, the web supply roll and the delivery, thatthe web can be fed and printed and the inks dried with a minimum travelof the web.

My invention comprises, generally, first and second multicolor printingunits, arranged side by side at one end of the press in substantiallythe same horizontal plane, each printing unit consisting of animpression cylinder and form cylinders arranged partway around the same;

first andsecgmd combined heating and cooling units in substantially thesame horizontal plane located side by side above the printing units,each combined heating and cooling unit comprising a heating cylinder andone or more cooling cylinders and a web supply roll located in line withthe first printing unit and first heating and cooling unit and belowsaid first heating and cooling unit; means being provided for passingthe web from the supply roll to and through the first units, then aroundturning bars to and through the second units, and finally delivering theweb at the other end of the press in line with the second printing unit.

A practical embodiment of my invention is represented in theaccompanying drawing, in

which Fig. 1 represents a diagrammatic top plan view; and

Fig. 2 represents a similar view in side elevation.

The first printing unit is herein represented.

as a five color unit, the impression cylinder being denoted by I and itsfive form cylinders by 2, 3, 4, 5,6, which form cylinders are arrangedpartway around the impression cylinder I. The inking mechanisms for theform cylinders are denoted by 2a, 3a, 4a., 5a, 6a.. The second printingunit for perfecting the web is herein represented as a five color unit,the impression cylinder being denoted by I and its five form cylindersby 8, 9, in, II, l2, which form cylinders are arranged partway aroundthe impression cylinder I. The inking mechanisms for the form cylindersare denoted by 8a, 9a, Illa, Ila, I2a.

These two printing units are arranged side by side at one end of thepress in substantially the same horizontal plane. The first combinedheat- (c1. lop-119) ing' and cooling unit is herein represented ascomprising a. large heating cylinder l3 and two small cooling cylindersl4, 15, arranged at one side of the heating cylinder (preferably theside toward the first printing unit) and spaced the 5 requireddistance-apart.

The second combined heating and cooling unit is herein represented ascomprising a large heating cylin'der l6 and two small cooling cylindersI'I, ll, arranged at one side of the heating cylinder (preferably theside toward the second printing unit) and spaced the required distanceapart.

These two combined heating and cooling units are located side by side insubstantially the same horizontal plane above their respective printingunits.

The web supply roll is denoted by I9 and it is located in line with thefirst printing unit and the first combined heating and cooling unit, andbelow the first heating and cooling unit.

The web is led through the press as follows: The unprinted web passesfrom the supply roll I9, to and through the first printing unit wherethe web is printed in multicolor upon one side thereof. The web isthenled to and and around the heating cylinder l3 and cooling cylindersit,

I 5 of the first combined heating and cooling unit. From thence thewebis led around a turning bar 20 laterally to and around a secondturning bar 2|. From thence the web is led to and through the secondprinting unit and from there to and around the heating cylinder l6 andcooling cylinders ll, it of the second combined heating and coolingunit. From thence the perfected web is delivered at the other end of thepress in line with the second printing unit and second combined heatingand cooling unit.

The means for driving the several units is not shown or describedherein, it being understood that the first and second units may bedriven separately either for the purpose of making ready or forpermitting a single or two separate non-perfected multicolor products tobe produced.

- i It will also be understood that any well known or approved quickdrying may be used in'the printing units.

combined heating and cooling units located side by side, .a web supplyroll'located in line with the first printing and first heating andcooling units, and means for leading the web through the first andsecond'units and delivering the web.

' 2. In a web perfecting rotary press, first and second multicolorprinting units located side by side at one end of the press, first andsecond combined heating and cooling units locatedside by side, a websupply roll located in line with the first printing and first heatingand cooling units, and means for leading the web through the first andsecond units and delivering the web at the opposite end of the press-inline with the second printing and second heating and cooling units.

3. In 'a web perfecting rotary press, first and second multicolorprinting units located side by side at one end or the press, first andsecond combined heating and cooling units located side by side, a websupply roll located in line with the first printing and first heatingand cooling units and below'the first heating and cooling unit, and

'means for leading the web through the first and second units anddelivering the web.

4. In a web perfecting rotary press, first and second multicolorprinting units located side by side at one end 0! the press, first andsecond combined heating and cooling units located side by side, a websupply roll located in line with the first printing and-first heatingand cooling units and below the first heatingand cooling unit, and meansfor leading the web through the first and second units and deliveringthe web at the oppo-- site end or the press in line with the second Dintingand second heating'and cooling units.
